High-Efficiency Water Drum Filter for Industrial Waste Water Treatment
Inner feeding rotating Drum Filter Overview The internal water drum filter is a new type of drum screen filter. It is suitable for separating the impurities (small suspended matter, fiber, distiller's grains, pulp, etc.) in the liquid to the maximum extent to achieve the separation of solid and liquid phases. The difference between the internal water drum filter and other methods is that the filter medium has a particularly small gap. and the centrifugal force of the screen rotation has a high fluidity at a low water resistance, and the suspended solids are trapped. The equipment is specially developed for the problems that the existing microfiltration machine is easy to block, easy to break, large maintenance and maintenance workload, and secondary investment. A new type of microfiltration machine developed with the help of foreign excellent technology and developed for China's national conditions, is widely used in various occasions where solid liquid separation is required. working principle The working principle is to treat the water from the water pipe into the overflow water distribution device. After a short steady flow, the water outlet evenly overflows and is distributed in the filter filter screen rotating in the opposite direction. The water flow and the inner wall of the filter cartridge produce relative shearing motion. The water efficiency is high, the solid matter is intercepted and separated, tumbling along the spiral guide plate in the cylinder, and discharged from the other end of the filter cartridge. The filtrate flows away from the sink. The machine is equipped with a flushing water pipe outside the filter cylinder, and the flushing water pressure (3kg/cm2) is fan-shaped to flush the dredging filter to ensure that the filter screen always maintains good filtering capacity. device installation (1) Installation preparation First organize the installation personnel to be familiar with the structure, function and characteristics of the equipment. And pay attention to the descriptions and requirements in all technical materials. Check the equipment for defects. According to the basic structure drawing, the foundation surface is flat, and the reserved hole spacing and vertical deviation are not more than 10 mm. (2) Description of the installation process After the foundation is installed, the base surface and bolt holes should be cleaned, the
